In their study of driver education practices, the authors investigated the relative effectiveness of four selected driver and traffic safety education laboratory programs, three selected driver and traffic safety education classroom programs, and sought to determine if the effectiveness of a program is affected by the sex of the student. The experimental population was pretested, exposed to the various programs under study, and then tested for driving performance, driving knowledge, and traffic analysis. The results of analysis of data obtained in the study suggests that certain practices and methods may be more efficient than others and that there is a sex differential in driver knowledge. Included in the appendices are a bibliography, a sample of the various lesson plans and teaching methods, and information on the research methodology.
